Abstract
A particulate material production method is provided. The particulate material production method includes ejecting a particulate material composition liquid, which includes an organic solvent and a particulate material composition including at least a resin and dissolved or dispersed in the organic solvent, from at least one nozzle to form droplets of the particulate material composition liquid in a gas phase; and solidifying the droplets of the particulate material composition liquid to prepare particles of the particulate material composition. The droplet solidifying step includes contacting the droplets with a poor solvent for the particulate material composition.
